Nearly every cell in our bodies carries the same genetic code. Yet different types of cells read the same DNA in widely different ways, influenced by chemical chemical tags that modify the genetic material without changing the underlying DNA sequence. Scientists today announced significant progress in the unraveling of the…

UC San Diego School of Medicine researchers will receive $6.4 million in National Institutes of Health grant funding to study how external signals and genetic variations influence the behavior of one cell type in particular: insulin-producing beta cells in the pancreas.

UC San Diego biologists have uncovered a quality control timing mechanism tied to cell division. The “stopwatch” function keeps track of mitosis and acts as a protective measure when the process takes too long, preventing the formation of cancerous cells.

Researchers at University of California San Diego have discovered a process in which liver cells share molecules in order to multiply under conditions that would ordinarily suppress cell proliferation. They also found evidence that this process occurs in various types of cancer cells.

When a rapidly-growing cell divides into two smaller cells, what triggers the split? Is it the size the growing cell eventually reaches? Or is the real trigger the time period over which the cell keeps growing ever larger? A novel study published online today in the journal Current Biology has…

…of scientists headed by biologists at UC San Diego has discovered that an important class of stem cells known as human “induced pluripotent stem cells,” or iPSCs, which are derived from an individual’s own cells, can be differentiated into various types of functional cells with different fates of immune rejection.

…at the intersection of biology and physics, scientists at UC San Diego have made a surprising discovery at the root of cell formation. They found that DNA executes an unexpected architectural role in shaping the cells of bacteria. Studying the bacterium Bacillus subtilis, the researchers used an array of experiments…

By applying mathematical models to a large number of experiments in which bacterial growth is inhibited, a team of physicists, biologists and bioengineers from UC San Diego developed a “general growth law” that explains the relationship between the average cell size of bacteria and how fast they grow.

Biologists at UC San Diego have found the “missing link” in the chemical system that enables animal cells to produce ribosomes—the thousands of protein “factories” contained within each cell that manufacture all of the proteins needed to build tissue and sustain life.

The first comprehensive map of the dramatic changes that take place in the blood system over the course of the human lifetime could have implications for the treatment of acute myeloid leukemia and other blood diseases.
